When your brain feels it need the drug to keep going. This is probably the biggest part of an addiction.
Actually the physiological aspects of addiction are twofold. There is the initial physical need for the substance which will cause you to feel withdrawal symptoms such as:
Alocohol: shaking hands, nausea, headache, thirst, dizziness (basic hangover stuff) or hallucinations and seizures in those severely addicted (aka The DT's).
Opiates: Heroin, Oxies, etc. Nausea. cramping, sweats, itching, etc.
Then there are also the secondary symptoms that have to do with the brain chemistry trying to right itself after prolonged use. There will be mood swings, anxiety, irritability, depression, mania, etc. depending on the substance. Because people who are addicted can actually permanently change their brain chemistry after long term use of a drug these symptoms may never go away which is why anti-depressants and mood stabilizers (which are non-narcotic, non-addictive and don't get you high) are very useful for addicts trying to stay sober. This is also why studies have reported that up to 70% of those with an addiction have some form of mental disorder such as depression. Weather the mental disorder came first or the addiction is still being debated.

A physiological addiction involves physical dependence on a substance, where the body develops tolerance and withdrawal symptoms. A psychological addiction is more focused on the mental craving and emotional attachment to a behavior or substance without necessarily involving physical withdrawal symptoms.
Most likely it is not a true addiction and is more characteristic of Obsessive Compulsive Disorder... A true addiction has a basis in some kind of physiological response.
The unpleasant, sometimes life-threatening physiological changes that occur, due to the discontinuation of use of some drugs after prolonged, regular use.
To keep it simple, physiological dependence occurs when the individual needs the presence of a chemical in his or her system in order to feel relatively normal. At that point, using has become less an option than a need. The entire addiction syndrome includes physiological dependence, but also social, emotional and spiritual issues that stem from the effects of the chemicals and the need to keep them flowing, such as lying, making excuses, stealing, loss of spiritual values such as compassion, forgiveness and joy, and so forth -- along with an overpowering fear that somehow the chemicals will not be available when needed, and the fear of withdrawal and the changes that accompany abstinence. Note: I use "chemicals" instead of "drugs" because some addictions are related to self-generated brain chemicals, not just stimulation from drugs.
No. There are arguments that a person can be genetically more likely to become addicted to substances. In order for addiction to occur the substance must be used, this creates either a mental (psychological) addiction to the substance and/or a physical (physiological) addiction. Physiologcial addiction requires the person to use the substance or they will experience withdrawl effects such as shaking, sweating, headaches etc. Psychological addiction invloves the person mentally thinking they must have the substance (ie. if i dont take the drug i wont be able to sleep) Hope this Helps!
Obsessive Compulsive disorder is where a person has an obsession, which creates intruding thoughts in their minds which are uncomfortable. For example, an obsession with germs, and constant thoughts that lots of things are contaminated. The compulsion is a behaviour which is done in order to remove the obsessive thoughts, e.g. hand washing. Therefore, it is different to an addiction, yet the compulsions are very difficult to stop -which is similar to addiction, whereby the addictive behaviour is hard to stop. Addiction on the other hand may be due only to the physiological need for a chemical, such as nicotine, and does not necessarily have to be caused by an obsession, as OCD is.

Most clinics will treat addictions for pain killers, opiates and narcotics; some have specialty facilities to treat methamphetamine addiction or alcohol addiction. Each clinic has its own policies on what they will and will not be able to treat.
Brooks Addiction is not some sort of drug addiction, or any other typical kind of addiction. The Brooks Addiction is simply just a type of shoe that is meant for walking.
